Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

open access: yesJournal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity

open access: yesJournal of Anatomy, EarlyView.
This study investigates the morphology, abundance, and distribution of taste papillae in the oropharyngeal cavity of a range of elasmobranchs using SEM, histology, and topographic analyses. The interspecific importance of gustation is reflected in quantitative differences in the size, density, and distribution of taste papillae, which have implications

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

open access: yesJournal of Anatomy, EarlyView.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Diversity and development of the hemibacula of croaking geckos (Sphaerodactylidae: Aristelliger)

open access: yesJournal of Anatomy, EarlyView.
Geckos in the genus Aristelliger exhibit enigmatic mineralized elements in their hemipenes, called hemibacula. We examined hemibacula of every species of Aristelliger using μCT, clearing and staining, and histology. We found hemibacula exhibit lineage‐specific morphology, isometric growth after sexual maturity, and are composed of mineralized ...

‘Vote the Assholes Out’: How Value Congruence Work Aligns Stakeholders for Corporate Activism

open access: yesJournal of Management Studies, EarlyView.
Abstract Recent research has pointed to value congruence between a firm and its stakeholders as a key driver of corporate socio‐political activism. However, this ‘stakeholder alignment’ model of corporate activism does not adequately explain how firms foster value congruence with their stakeholders.

Aging cheetahs using gum‐line recession and evaluation of expert‐based aging techniques

open access: yesJournal of Zoology, EarlyView.
Knowledge of animal age is important for population management of wildlife. We show for the first time how gum‐line recession of canine teeth can be used to age cheetahs. We also compare gum‐line recession estimates with expert opinion‐based aging and discuss cheetah age assignment techniques.
